    Quiet Communities, Inc. et al. v. United States Environmental Protection Agency et al., Case No. 23-cv-1649 (JMC) — Memorandum opinion and order

    A federal court ruled in 2023 that the EPA had unreasonably delayed for over 40 years in carrying out its legal duties under the Noise Control Act of 1972, which requires the agency to regulate environmental noise, publish noise-related reports, and help state and local governments develop noise control programs. Although President Reagan defunded the EPA's noise office in 1982, Congress never actually repealed the Noise Control Act, meaning the EPA's obligations under the law remained in force. The court granted partial summary judgment in favor of the plaintiffs, finding the EPA's inaction on four key counts unlawful.

    Quiet Communities, Inc. v. EPA: Memorandum Opinion and Order (Case No. 23-cv-1649)

    A federal court ruled in July 2026 that the EPA has unlawfully delayed carrying out its duties under the Noise Control Act of 1972, a law that has remained on the books even though the agency effectively shut down its noise control program in 1982 after Congress approved President Reagan's budget cuts. The lawsuit, brought by Quiet Communities, Inc. and Jeanne Kempthorne, argued that over forty years of EPA inaction on noise regulation violated the agency's legal obligations. The court granted partial summary judgment for the plaintiffs on four counts, finding the decades-long delay unreasonable, while dismissing other claims for lack of jurisdiction or failure on the merits.

    Puget Sound Region Final Comprehensive Climate Action Plan

    The Puget Sound Region Final Comprehensive Climate Action Plan, published December 1, 2025 by the Puget Sound Clean Air Agency, outlines greenhouse gas reduction strategies for King, Kitsap, Pierce, and Snohomish Counties in the Seattle-Tacoma-Bellevue metropolitan area. The plan covers six sectors—Built Environment, Transportation, Municipal Solid Waste and Wastewater, Natural and Working Lands, Refrigerants, and Consumption—with goals, emission projections, and workforce planning analysis. Note that this document focuses on regional climate and air quality policy rather than Sea-Tac Airport noise regulations specifically.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
